Abstract

Reaction of an aromatic dianhydride with a polycyclic aromatic primary diamine at a controlled reaction rate yields a diamic acid dianhydride oligomer. The oligomer may be a precursor for an imide foam which forms at a low temperature, has outstanding physical characteristics, and is extremely heat resistant. The diamic acid moiety may be converted to diimide, and other modifications of the oligomer are disclosed. Other derivatives of the oligomeres are also disclosed.
